TPMS - sensors or wheel speed?

Hello, just trying to sort out snow tires for this winter. Does anyone know if my car (2017 LX Canadian model) has actual TPM sensors in the wheels, or does it use the relative wheel speed (like VW / Audi) to determine if there is low pressure? Two dealers and a local tire shop couldn't tell me for sure without taking the wheels off.

Thanks!

You must have some crappy dealers up there in Canada. Took me only a couple of minutes to find it in the Service Manual.

Yes, there is a TPMS sensor in each wheel which sends an RF signal to the central TPMS receiver module.

Thank-you!

Both dealers I asked for the service dept, and at both the person on the phone said they didn't know but "parts" would. At the Parts dept, one guys said "uh I think so", when pressed he couldn't confirm. The other dealer's parts dept guy looked up in his computer and said he couldn't find the part, so therefor the car definitely didn't have them! Yet another reason why I hate dealers.

Yes you have sensors in each wheel. Part no. is 52933-B2100. Had to get a set when I changed the wheels on my van. Keep in mind you need to have to go to the dealer anyway to have the TPMS module recognize your new sensors, otherwise it'll trigger the light. It's not a self-learning system like on the higher-end Hyundai/Kia models.

Once the dealer registers the new set of TPMS sensors on the ECU do they continue to be recognized each time the wheels are swapped (summer to winter and vice versa)?

Does the TPMS system on a 2018 Sedona let you read the reported pressure in each tire? If not, when it detects low pressure, does it at least indicate which tire(s) it has detected the problem on?

Thanks,
Mike

Neither, its just an idiot light that pops up. The PSI pressure to trigger a light is pretty low (~20 psi I think), I would not rely on it if you're concerned about being a few PSI low of normal. Keep in mind, this is how most TPMS are setup from the factory- its there to primarily meet the NHTSA rules about having one.

You're better off checking regularly like you would on a non-TPMS car with a pressure gauge.

Thanks very much for the reply. I had called Kia with this question, and the product specialist that I spoke with didn't know. She said that she would try to find out and get back to me, but so far I have not received an answer from Kia. However, she did say that regardless of whether the individual tire pressure readings can be displayed on the dash, she believes that they can be viewed on a smartphone via the UVo app.

Do you know whether this is correct? It sounded a little strange to me that they would be viewable in the app but not directly on the dash.

Thanks,
Mike
